Raw physical properties measured on sediment core GeoB22331-2

Sound knowledge about the petrophysical characteristics of a sediment core is a prerequisite for any subsequent paleoenvironmental study relying on sediment proxies. Physical properties of whole-round sediment cores are acquired as a first step of sediment core description, prior to slicing of sediment cores into two halves. Here, we present raw physical-properties data of core GeoB22331-2 acquired with a Geotek MSCL-S system on the unsplit core, retrieved during RV Maria S. Merian expedition MSM66 WESTBAFF to the Baffin Bay, Canada/Greenland, in 2017.

透彻掌握沉积物岩芯（sediment core）的岩石物理特性，是后续所有依托沉积物代用指标开展古环境研究的必要前提。完整沉积物岩芯的物理特性数据采集，是沉积物岩芯描述工作的首要步骤，需在将岩芯切割为两半之前完成。本文公开了岩芯GeoB22331-2的原始物理特性数据，该数据由Geotek MSCL-S系统在未拆分的岩芯上采集所得。该岩芯采自2017年加拿大与格陵兰附近的巴芬湾海域，由“玛丽亚·S·梅里安号”科考船的MSM66 WESTBAFF航次获取。
